Read the text about sundials and decide if the statements are True or False.
What do you usually use to know what time it is? You can use your phone or your watch. But many years ago, people used other things to know the time.
How can you know the time without your phone or watch? You can use the shadow!
When you are outside, look at your shadow. It changes the length in the morning, afternoon, and evening. It happens because the Earth turns around every day. The Sun changes its position in the sky at different times of the day. That's why you can use a solar clock to know what time it is.
You can make a solar clock yourself, but you need to have a few things: a straw, a plastic cup and a lid, stones, a compass, and a pen. Put some stones in the cup and close it with the lid. Put a straw inside the lid. Place your clock on the ground or a table. Point the straw to the North. Mark hours on the lid with the pen.
Choose the correct option.

Your shadow always has the same length. **** [True|False]
You need to point the straw to the South while making your own solar clock. [True|False]
